Summary

Nanoparticles containing antibiotic were prepared and incorporated in in situ gel to treat recurrent endodontic infections

Detailed description

Enterococcus faecalis is the main cause of endodontic infections and form biofilm on dentin, resulting in treatment-resistant periradicular lesions. To overcome these problems, antibacterial nanoparticles were used because of their small size, sustained release and positive charge which interact with the negatively charged surface of bacterial cell causing its destruction. In this light, Ciprofloxacin hydrochloride (CIP) in chitosan coated PLGA nanoparticles (CIP-CS-PLGA-NPs) and free CIP were embedded in Pluronic® 407/188 to form thermosensitive gels(F1) and (F2) respectively, that were investigated in terms of viscosity, gelation temperature and in-vitro release. The antibacterial efficacy of F1 and F2 were clinically investigated on patients then compared to CIP and Ca(OH)2 pastes by determining bacterial reduction percent and biofilm inhibition assay
